NAACCR XML: Tumor.brainMolecularMarkers
Description
Multiple brain molecular markers have become standard pathology components necessary for diagnosis. This data item captures clinically important brain cancer subtypes identified by molecular markers that are not distinguishable by ICD-O-3 codes.
Rationale
Collection of these clinically important brain cancer subtypes has been recommended by CBTRUS.
Codes
| 01 | Diffuse astrocytoma, IDH-mutant (9400/3) |
| 02 | Diffuse astrocytoma, IDH-wildtype (9400/3) |
| 03 | Anaplastic astrocytoma, IDH-mutant (9401/3) |
| 04 | Anaplastic astrocytoma, IDH-wildtype (9401/3) |
| 05 | Glioblastoma, IDH-wildtype (9440/3) |
| 06 | Oligodendroglioma, IDH-mutant and 1 p/19q co-deleted (9450/3) |

Each Site-Specific Data Item (SSDI) applies only to selected primary sites, histologies, and years of diagnosis. Depending on applicability and standard-setter requirements, SSDIs may be left blank.
